I believe the answer is:
Review and Revue
Review is what you do to memorize, scan pages, or see something again. Revue is theatrical entertainment consisting of a series of sketches, songs, and dances.
To memorize or to see again
You would review something to memorize it, and to take a second look to ensure accuracy.
It still will sound the same
Review and Revue sound the same.
You would do this for a concert
You could review a concert, but a revue is also a concert of sorts.
Or you might if you reread a book, You would do this to all the pages
You are certainly reviewing the content of the book.
